lizgdal,

We must be talking about two different things. I'm not interested in that Nasdaq graph. I am trying to reconstruct Robbie's BCC signal which clearly is derived from SPY closing prices. I am currently working on the part that has to do with New Highs and New Lows which GTR1 shows as:

Create [PcntNHC252]: [100*[[Sum [[[Closing g-price; quote_lag=0 days]/[Highest closing g-price over 251 days; lag=1 days]] > 1 ? 1 : 0] at step4]/[StockCount]]]
Create [PcntNHC252WMA9]: [[Weighted Sum of [PcntNHC252] over 9 days (daily weights=9,8,7,6,5,4,3,2,1); lag=0 days]/[Weighted Sum of [1] over 9 days (daily weights=9,8,7,6,5,4,3,2,1); lag=0 days]]
Create [PcntNLC252]: [100*[[Sum [[[Closing g-price; quote_lag=0 days]/[Lowest closing g-price over 251 days; lag=1 days]] < 1 ? 1 : 0] at step4]/[StockCount]]]
Create [PcntNLC252WMA9]: [[Weighted Sum of [PcntNLC252] over 9 days (daily weights=9,8,7,6,5,4,3,2,1); lag=0 days]/[Weighted Sum of [1] over 9 days (daily weights=9,8,7,6,5,4,3,2,1); lag=0 days]]
Create [NHNLDiff]: [1*[PcntNHC252WMA9] - 1*[PcntNLC252WMA9]]

I see I still have to bring the part about [PcntNHC252WMA9] so my nap time revelation as I described earlier is not quite complete.
